PRODUCT DESCRIPTION The SST 25 series Serial Flash family features a four-wire, SPI-compatible interface that allows for a low pin-count package which occupies less board space and ultimately lowers total system costs. SST25VF032B SPI serial flash memories are manufactured with SST’s proprietary, high performance CMOS SuperFlash technology. The split-gate cell design and thick-oxide tunneling injector attain better reliability and manufacturability compared with alternate approaches. FEATURES: • Single Voltage Read and Write Operations – 2.7-3.6V • Serial Interface Architecture – SPI Compatible: Mode 0 and Mode 3 • High Speed Clock Frequency – 80 MHz Max • Superior Reliability – Endurance: 100,000 Cycles (typical) – Greater than 100 years Data Retention • Low Power Consumption: – Active Read Current: 10 mA (typical) – Standby Current: 5 µA (typical) • Flexible Erase Capability – Uniform 4 KByte sectors – Uniform 32 KByte overlay blocks – Uniform 64 KByte overlay blocks • Fast Erase and Byte-Program: – Chip-Erase Time: 35 ms (typical) – Sector-/Block-Erase Time: 18 ms (typical) – Byte-Program Time: 7 µs (typical) • Auto Address Increment (AAI) Word Programming – Decrease total chip programming time over Byte-Program operations • End-of-Write Detection – Software polling the BUSY bit in Status Register – Busy Status readout on SO pin • Hold Pin (HOLD#) – Suspends a serial sequence to the memory without deselecting the device • Write Protection (WP#) – Enables/Disables the Lock-Down function of the status register • Software Write Protection – Write protection through Block-Protection bits in status register • Temperature Range – Industrial: -40°C to +85°C • Packages Available – 8-lead SOIC (200 mils) – 8-contact WSON (5 X 6 mm) • All devices are RoHS compliant
GENERAL DESCRIPTION The W25Q32DW (32M-bit) Serial Flash memory provides a storage solution for systems with limited space, pins and power. The 25Q series offers flexibility and performance well beyond ordinary Serial Flash devices. They are ideal for code shadowing to RAM, executing code directly from Dual/Quad SPI (XIP) and storing voice, text and data. The device operates on a single 1.7V to 1.95V power supply with current consumption as low as 4mA active and 1µA for power-down. All devices are offered in space saving packages.
